Hypothesis pattern breaks and freezes the whole system

[mosoriob]

Describe the bug

The SPARQL query generated by the following hypothesis pattern is too heavy. (117,649 entries)

SELECT DISTINCT * 
FROM <http://endpoint.mint.isi.edu/temp/data/>
WHERE { 
?goal hyp:associatedWith ?WeatherSensor1.
?goal hyp:associatedWith ?WeatherSensor2.
?goal hyp:associatedWith ?WeatherSensor3.
?goal hyp:associatedWith ?WeatherSensor4.
?goal hyp:associatedWith ?WeatherSensor5.
?goal hyp:associatedWith ?WeatherSensor6.
}

Problems:

1. The query doesn't end because ontapi doesn't support timeout
2. If the query ends, generate 117,649 matches.
